I ran across one at a gun show a few months ago for $699. I happily snapped it up for that price. Its been 100% great so far, and in my opinion is a very handsome gun.
But don't let impatience bait you into paying $800+. The Ruger is a nice, reliable, basic 1911. But once you start getting closer to $800+, you can probably do a bit better with a higher grade Springfield, Sig, classic Colt, etc.
